Fig 7. Population genetic structure of Triatoma dimidiata across Central America inferred with a discriminant analysis of principle components (DAPC) based on SNP markers.

DAPC shows the maximized differences among four genetic clusters of the vector. Clusters were determined using the k-mean clustering algorithm and choosing the lowest Bayesian Information Criterion (BIC). Ellipses show 95% confidence intervals. The first two eigenvalues explain 69.2% of the variation found in 21,461 SNPs.
